What is Harrod-Domar model of growth?
The Harrod–Domar model is a Keynesian model of economic growth. It is used in development economics to explain an economy’s growth rate in terms of the level of saving and of capital. It suggests that there is no natural reason for an economy to have balanced growth. The model was developed independently by Roy F.
What is Harrod-Domar model equation?
economic growth and development this can be expressed (the Harrod–Domar growth equation) as follows: the growth in total output (g) will be equal to the savings ratio (s) divided by the capital–output ratio (k); i.e., g = s/k.
What is the difference between Harrod and Domar growth model?
Domar’s model is based on balanced technique of growth while Harrod’s growth model moves from balanced technique to balanced technique. 7. Harrod’s model is based on the principle of acceleration, while Domar’s model of growth is based on the principle of multiplier.
How does the Harrod-Domar model work and why it is important?
The Harrod Domar Model suggests that the rate of economic growth depends on two things: Level of Savings (higher savings enable higher investment) Capital-Output Ratio. A lower capital-output ratio means investment is more efficient and the growth rate will be higher.
